>Is any way to disable the VFP Runtime caption when the compiled application started? (Caption VisualFoxPro) or change it to my custom caption?

Include a CONFIG.FPW in your project with the line SCREEN = OFF in it, and then set _Screen.caption to whatever you like before making the _screen visible (_screen.visible = .t., _screen.show(), etc.) - you can also use a top-level form and never make the VFP main screen visible at all.
